Cost of Using FLUOrescence to Green of Indocyanine for the Detection of Breast Cancer.

The main objective is to evaluate the overall cost at 1 month of the sentinel lymph node detection technique using Indocyanine Green compared to the technique using isotopes in patients with breast cancer, from the point of view of health insurance and the hospital.

The chosen time horizon is up to 1 month post-intervention. The choice of this time horizon corresponds to the usual duration of follow-up for patients who have benefited from one of the sentinel lymph node detection techniques, in order to collect the main post-surgical complications.

This is a multicenter, prospective, observational, non-randomized study, aimed at comparing the overall cost of two sentinel lymph node detection techniques (Indocyanine Green and isotope) from a dual perspective (health insurance and hospital).
